Description

Dual wall heat shrinkable tubing is a 3:1 shrink ratio, flexible tubing, offering the advantages of integral, adhesive-lined construction. The tubing is made from flame retardant, flexible cross-linked polyolefin with an internal layer of excellent hot melt adhesive. The heat-shrinkable outer wall is durable, while maintaining the high flow and excellent adhesion of the inner sealant liner. When heated in excess of 125ºC (257ºF), the tubing rapidly shrinks to a skintight fit, forcing the melted adhesive lining to flow and cover the underlying surface. The adhesive forms a flexible bond with a wide variety of rubbers, plastics and metals. Upon cooling, the adhesive solidifies, forming a permanent, non-drying, flexible and water resistant barrier. 

 

Length

The lengths offered in this listing are 12 inch (1 foot) pre-cut lengths. The tubing is precut to simplify shipping. We cannot provide continuous length tubes so a quantity of 6 would be 6 one foot tubes. The tubing is easily cut to your preferred length with scissors or razor blade but a razor blade cut on a flat surface is the preferable way for cuts to be made. Longitudnal shrink ratio is less than or equal to 8%

Applications

Dual wall adhesive heat shrink tubing offers excellent environmental protection for electronic components, wire splices, wire bundles and harness breakouts. Automotive, truck and marine wiring splices and harness breakouts are quickly and easily protected from harsh environments.

 

Shrink Ratio

Our dual wall heat shrink tubing has a 3:1 shrink ratio. When freely recovered, the tubing will shrink 33% of its as-supplied diameter. The recovered wall thickness of the tubing is proportional to the degree of recovery. The continuous operating temperature range is from -45ºC (-49ºF) to 125ºC (257ºF), with a shrinking temperature minimum of 125ºC (257ºF).
